WebJan 18, 2024 · AAPG Store. The most direct way of finding water resistivity ( Rw) is to obtain a sample of formation water and measure its resistivity. However, this is seldom possible in practice, as formation water samples, if available, are invariably contaminated by mud filtrate. Rw is therefore usually calculated, and there are three methods available ...
WebIf we compare wires made of different materials, say copper and aluminum, we find that for a given applied voltage, more current flows through the copper wire than the aluminum wire. We say the aluminum has a higher resistivity . In a conductor the current and current density are proportional to the applied electric field.
